Description
The TSB Series is a totally solid-state, delay-on-break timing module. The TSB series is available with a fixed, external, or onboard adjustable time delay. Time delays from 0.05 to 600 seconds, in 4 standard ranges, cover over 90 % of all OEM and commercial appliance timing applications. The repeat accuracy is ±2 %. Operating voltages of 24, 120, or 230 V ac are available. The TSB’s 1 A steady state, 10 A rated, solid-state output is perfect for direct control of solenoids, contactors, relays, lamps, buzzers, and small heaters. The TSB series can be surface mounted with a single screw, or snapped on a 35 mm DIN rail using the P1023-20 adapter. Operation (Delay-on-Break) Input voltage must be applied before and during timing. Upon closure of the initiate switch, the output energizes. The time delay begins when the initiate switch opens. The output remains energized during timing. At the end of the time delay, the output de-energizes. The output will energize if the initiate switch is closed when input voltage is applied. Reset: Reclosing the initiate switch during timing resets the time delay. Loss of input voltage resets the output and the time delay. Features & Benefits FEATURES BENEFITS Analog circuitry Repeat accuracy + / - 2 %, Factory calibration + / - 5 % T otally solid state and encapsulated No moving parts to arc and wear out over time and encapsulated to protect against shock, vibration, and humidity Wide time delay range Meets almost all OEM and commercial appliance timing applications 1A steady, 10A inrush solid state output Provides 100 million operations in typical conditions Accessories P1004-95, P1004-95-X Versa-Pot Panel mountable, industrial potentiometer recommended for remote time delay adjustment. P1023-6 Mounting bracket The 90° orientation of mounting slots makes installation and removal of modules quick and easy.
